This invention relates to improvements in valve separator machines and more pai'- ticularly to novel methods and improved devices for removing valves lfroin rubber tires and the like and tor separating the iron portions of the valves from the brass portions.

An object of theA invention is to provide a valve separator machine which is especially adapted for removing valves 'form the inner tubes of automobile tires and the like.

Another object of the invention is to provide a valve separator machine which is adapted to remove the valve Vstem from the tube and to separate the iron portion of the valve from the brass portion by a single operation of the machine.

A further object of the invention the provision of a machine of the classdescribed which is simple in construction, easily operated and adapted for economical manufacture. y

A still further object is the general improvement of valve separator machines ot the class-described.

lVith the above and other objects in view, the invention consists in the novel methods and in the typical details ot construction' and in the arrangement and combination of parts hereinafter more ft'ullyV described and particularly pointed out in the appended claims.

ln describing the invention in detail, reierence will be had to the accompanying drawings, wherein like characters of reference denote corresponding parts in the several views, and in which Figs. 1 and 2 are respectively front and side elevational views of the machine;

Fig. 3 is a plan view oi the machine;

Ll is a view along the line 4 4 of Fig. 1;

Fig. 5 is an enlarged sectional view of a portion ci the machine showing an inner tube in position for removal of the valve therefrom; and

Fig. 6 is a view along the line Fig. 3.

Referring to Figs. 1 and 2 oi' the drawings. the machine comprises a supporting frame 1() having a crank shaft 11 mounted thereon. The shaft 11 is carried by two bearings 18 between which is located a sliding box 14, shown in sectional detail in Fig. 6. A i head 15 mounted on the sliding c c @f box 14 and extends downwardly inside a way 16, the iront of said way being covered by a plate 17.

' The supporting` trame carries the parts vot a die couple which are'movable relatively Vc arryinga die 22, which is normally positioned immediately beneath the punch member. A knife 28,"carried by the T head 15, is mounted gustbaclr of the punch block 18. The lriiiife 23, cooperates with the punch member and extends downwardly substantially the saine distance as does the punch 2O2 the purpose and function of the knife` vbeing hereinafter more particulirlyV eX- plained.

A driving wheel 12 is mounted upon one end oi' the shaft 11 and is freely rotatable thereon. rlhe wheel 12 is operatively connected in any convenient manner with a source of power, not shown, and rotates substantially continuously `while the machine is in use. y i

The die block 21 with a tube 24, operatively positionedl on the bloclr., are shown in detail to an enlarged scale in Fig. 5, with a" valve which is to be removed from the tube, extending down through the die 22. The valve, which is to be removed from the tube 2st and separated into its component parts by one operation, is made up ot the usual parts. lThese parts include a threaded valve housing 27 and an inner washer 26, both manufactured oi' brass, and an outer iron washer or retaining member 25, Vall of which are tightly and firmly connected so as to require great pressure to separate them; y

ln its operative position the die 22 is positioned immediately underneath the punch 20 and in close proximity thereto in order that vertical movement of the punch be kept at a minimum. rifhe close proximity of the die 22 and punch 2O makes it desirable that the die be removed tromunderneath the punch for the purpose oit locating the tube 24 on the die. For this purpose the die 22 is mounted on the upper end of a vertically extending auxiliary traine 28 having a pedal 29 at- Vthe pedal 29.

l taclied to the lower end thereof. The frame 28 is pivotally mounted on a pin 30 which permits the die 224 to be moved lateinlly'to-` wardsthe Voperator by exerting pressure on A te-nsile spring 3l provided to pull the frame 28 back to its non4 -mal position, when the pedal 29 isl re leased, thereby carrying with it the die 22 andthe tube 24 which has been positioned thereon.

i The returninovement ofthe frame 28 t'o its original upright position sets in motion a device which connects the T head 15 with the vdriving wheel l2 andthereby actuates .the punch 20, causing it to` move downwardly from its normal position as is best shown in Figxp, to, a. position where it contacts with and forces the valveV out of the tube l24 `and into'its component parts as hereinafter more particularly described. 'lhe` device which starts the punch 2O in motion includes a. clutch trip4 member 32 which is-fastenedtov theframe28 by bolts 34.V

The v,member 32 extends rearwardly where it contacts with and actuates a punch rod 35 ywhen the frame28 is returned to its vertical .y position.

',Tlie rear end of the trip member-32 is provided with a lug 36 which has its-outer edge or face beveled. Afinger '39, having its l forward Vface beveled, is pivotally mounted on the lower end. of the punch rod 35by means of a bolt 40. The linger 39 is Vfree to rotate from itsV vertical positiontowards the operator and back to its vertical position, as shown in Fig. 2, butis prevented from movingpalst its vertical position in the opposite'direction by the `provision of suitablemeans such as a lug (not shown). f The lug1 is not shown as it is a common and Well known device for limiting rotationand` is not apart of theV invention'. A1- guide nieiii- Yber 37 is bolted to the side of the frame 10.

The rod 35 passes through the member 37,

the latter serving -to prevent all motion ofthe rod 35 other than in alongitudinal direction. yA tensile spring. 38 connects the upper end vof the rod `35 withthe guide member 37 and yieldingly .holds the rod ..35 in the position shown .iirFig 2.

TWhen. the operator presses down' on theV pedal 29 and thereby moves the fraine28 outwardly, the trip'meinber 32 is carried by the verticalframe28 to the dotted line posi- Vtion of Fig. 2. InV moving Vthe lug-36 forwardly, thenger 39 gives way before the lug 36 and drops vdown again to its vertical position after thelugfhas passed. Upon releasing the pedal 29, the frame 28 .returns to its normal vertical position carrying with it the trip member 32 and thereby brings the beveled face ofthe lug36 into contact with the beveled'edge of the finger 39. Since the finger 39 can not swing or Vyield beyond its vertical position, the pressure of the lug36 wheel12,with-thecranlr shaft lll. p

purpose thefcrank'shaft 1l has a longitudiforcesthe rodV 35, oi'i'whichthe linger 39 is mounted, upwardly `aga-inst the Vtension of the spring 38, sufhciently to let the lug pass to its full line position as `shownin Fig. 2.

'VVh'en theV luv 36 has reached its normal position, the spring38 pulls the rod `35 and linger 39 Vback tothe iosition shown.

A@ Y. ,n .The upward movement or the punch rod 35, caused by the inward movement of the frame 28, and the doiii'nward iiiovr-.uiient` of the rod 35 which is caused by the pull ofthe spring 38, produces a Vcycle of operations resulting in one complete actuation Vof the punch 20, this result being at v son of the connectionof'the rod 35 with a device adapted for connecting the driving` For this nally extending key42 which normally completelyrecessed therein with. one endcf the key' in close proximity to theV driving wheel.l 12. l recessed position, Vpermits the wheel l2 to rotate about the shaft, beingheld in said recessed position inthe shaft 1lb); alug44. The lug 44 is fastened 'onY one vend .of a rod .45 which' is rotatably mounted. ina iiiain Vguidelug 46, the lug 46 being shown as intertained by reno.

Thekey 42, whenin its norinally` grally formed with the frame l0.V The` 4punch rodv 35 isfconnected to the other end of thev rod 45 means of` an'eccentric collar 47 as shown in Figs. 2, 3 and v(i,whereby vertical motion ofthe rod 35 producesl corresponding oscillation of the rod 45 and Vthe Y ioo 111g 44.- y A The punch rodl 35 is shown in Figx4, in its extreme uppermost position. This po.- sitionv results from the thrust of the lug 36 againstv the finger 39, as previously described,

shown in Fig. 4. VTherod 45 is heldin adjustableV longitudinalposition by collars 49 and 50, positionedone on eitherside ofthe main guide lug 46; Y

A pair of pins v5l are mounted in.. the hub of the wheel 12 and project suliiciently'that the nearest will engage thek key 42 when the key is in the position shown in Fig. 4. Thel pins 5l clear the key 42 when the. key is in Y its normally recessed position in the `shaft l1. The contacting faces of the'key 42 and of the lug 44 are beveled and, 'when the lug 44 is returned to its normaly position ofl close contact with the Ashaft 11, the key 42 is forced back, against the pressure of the spring 43, to its innermost recessed position in the shaft l1. The engagement of the pins 51 with the key l2 will thus cause one complete rotation of the shaft 1l upon release of the key and, it", during this rotation of the shaft, the lug elfi is returned to its position of close con tact with the shaft, the key will be forced back into its normal recessed position at the completion of the first rotation andthe shaft l1 ivill come to a stop with the lcy Ll2 uuderlying the lug' del. To insure the stoppage of the shaft 11 with the lrey l2 in its recessed position, a brake 52 is provided which retards the shaft and brings it to an abrupt stop as soon as the lrey is released from contact With the pin l. rEhe brake 52 is adjusted by means of a brake knob 53.

A complete cycle of operations resultingin the removal of the valve from the tube and the separation of the brass portions of the tube from the iron portion thus results from moving the die 22 out from under the punch 2() by the operator exerting pressure upon the pedal 29, following this with positioning the tube as shown and then releasing the pedal. r1`he spring 31 pulls the frame 28 and the die 22 back to their normal position and cause the lug 36 to force the iinger 39 and the punch rod 35 upward sulficiently to permit the lug to pass under the finger. The rod 35 remains in this upper position for only an instant-but during` this instant the lug la has been turned to the position shown in Fig. fl, and the keyv1l2 has moved to its unseated position therein shoyvn. The resulting engagement of the pin 5l with the key l2 causes the shaft 11 to rotate with the wheel l2. The lug` 44 is immediately returned to its position of` close contact with the shaft 11 by reason of the downward movement of the rod 35, which follows close after the passing of the lug' 36 under the iinger 39, this movement being` expedited by the pull of the tensile spring 3S upon the rod 35.

The substantially instantaneous return of the lug 1l/l to its position of contact iv'th the shaft forces the key Zl2 back into its recessed position upon completion of one revolution of the shaft 11 with the wheel 12. The dis engagement of the ley a2 from the pin 51 prevents further rotation of the shaft 1l. rllhe retarding` effect of the brake 52 brings the shaft 11 to an inin'iediat-e stop with the lug' elli in operative Contact With the hey 42 whereby the lrey is held in its recessed posi tion until another cycle of operations is started by the release of the pedal 29.

rihc slidingv box 14 and the '1" head 15 are so mounted upon the shaft 11 that, during` the first half of the revolution of the shaft, the T head 15 is forced doivnivardly carrying with it the punch block 1S and the punch 20. The punch 2O is thereby brought into cont-act with the tube 2a and forces the punch through the tube into Contact .with `the valve stom 27V at its juncture with the brass Washer 26. The punch-" is carried by the operation down to a point Where the valve stein 2T is `forced free from the brass Washer 26 and free from the retaining inember or iron Washer 25,. after which it drops thro ugh the die 22 into a trough si-,suitably positioned to receive and carry ol'i' the saine. ilheilnife 23 is sin'iultaneously carried down and pierces the tube adjacent to the valve connection.V During the secondhalf of the rotation of the shaft l1, the T head 15 is carried to its extreme upward position whereby the punch 20 and the knife 23 are removed from conta-ct with the, tube. The brass washer 26 is then removed from the tube through the slit, resulting from the knife 23 piercing the tube, and are dropped into the trough 5a With the brass member 27 or otherwise disposed of as desired. The

tube 2st is then removed from its position on the die 22 and the iron Washer i5 disposed of in any suitable manner thereby completingr` the operation.

'lhus it will be seen that 1 have provided a device which is adapted to remove the valve from al tube or the like and to separate the brass portions of the valve from the iron portion at one operation.
